Still using jagged little strips of metal to unlock your front door? Paying someone to feed your pets while you’re away for a weekend? Then it’s time to truly enter the second decade of the 21st century. Setting up home-control automation that runs from your Mac and iPhone is surprisingly simple, and the results can feel like magic. We kick things off with a primer that takes the hassle and jargon out of home control, then dive straight into showing you the best possibilities for managing your home’s lights, entertainment, security, and loads more. Just wait until you check out the washing machine that tweets when it’s finished a load…

What Exactly is Home Control?

You might’ve also heard it called “home automation,” and you might be a bit reluctant to slog through all the jargon and devices that the phrase brings to mind. But really, it’s simple. There are two types of home-control systems: the fantasy technology you see at Disney’s Tomorrowland and the gear you can actually deploy in the real world. Unfortunately, manufacturers of home-control systems have overpromised and under-delivered for so many years that many people have just stopped listening.

Good news: It’s safe to start listening again. There’s still a yawning chasm between fantasy and reality--we’re a long way from having a robot butler greet us with our smoking jacket and a perfectly muddled mojito as we step out of our flying car. But we can manage nearly every system in and around the home: lighting, heating and cooling, home theater, security, even irrigation.

Why bother? Home-control systems are appealing for many reasons: They deliver unparalleled convenience and efficiency, they add value to your home, they strengthen your home’s physical security, and they help reduce your impact on the environment. With the right tools, you can monitor and manage all your home systems whether you’re on the couch, in the car, or at work. We’ll discuss those specific applications in the following pages, but first, it’s important to begin with an overview of the basics. Which home-control standard do you want to use? There are four major ecosystems to choose from, and naturally, they’re mutually exclusive (at least for the time being)…

X10/Insteon

Introduced by Pico Electronics way back in the 1970s, X10 is the granddaddy of home-control technology. The passage of time and the long absence of significant competition helped X10 amass the largest installed base of any home-control technology, despite a reputation for being as reliable as a British sports car from the same era.

X10 devices use a primitive form of power-line networking, meaning commands travel over your home’s existing electrical wiring. The X10 protocol doesn’t include a feedback loop, so there’s no way for devices sending commands to know whether those commands have been received and executed. The technology is also highly susceptible to electrical noise, which X10 devices sometimes interpret as valid commands. This can result not only in false negatives (a light or an appliance doesn’t turn on or off in response to a command), but also false positives (turning on or off in the absence of a command).

Insteon, developed by SmartLabs (a major distributor of X10 products) in 2001, builds and improves on the X10 protocol without rendering X10 devices obsolete. Like the ZigBee and Z-Wave standards we’ll discuss next, every node on the Insteon network is capable of receiving information and passing on the command to the next node if it’s not the intended target. Unlike those two standards, Insteon devices use both radio frequencies (RF) and power lines to communicate (this retains X10 compatibility and reaches devices where radio waves can’t penetrate).

SmartLabs' Insteon uses radio frequencies and power lines to communicate.

SmartLabs maintains its own online retail operation and sells directly to the do-it-yourself market. The Insteon ecosystem is extremely robust in terms of the systems it can manage. You can buy plug-in and in-the-wall lighting controls; thermostats; motion, door, and window sensors; irrigation controllers; and more. Third-party support is very good in some respects and surprisingly limited in others. For instance, you’ll find a number of Mac software controllers (see below), but none of the major lighting-control manufacturers in the U.S. (Cooper Wiring Devices, GE, Intermatic, or Leviton) build Insteon-compatible switches, dimmers, or receptacles.

Insteon’s failure to gain support from other manufacturers will likely limit its long-term prospects. The development of a bridge (a device capable of translating commands from one standard to another) would save Insteon customers from getting hosed if the market ultimately embraces one of the other competing standards.

ZigBee

ZigBee is the only home-control specification based on an IEEE standard (IEEE is the leading standards organization for device manufacturers; you’ve likely heard of its 802.11 standard for wireless networking). And you might think ZigBee’s designation as an international standard would automatically render it the marketplace winner (after all, how many wireless-networking products buck 802.11?), but far fewer ZigBee products are available to the do-it-yourself crowd than either Insteon or Z-Wave.

Part of the problem is that early versions of the ZigBee standard didn’t guarantee interoperability; companies were allowed to develop products that worked only within their own proprietary systems. ZigBee does have a strong presence in the energy-consumption and -management market, where it’s embedded in thermostats inside the home and in utility smart meters outside it. One of the largest home-control manufacturers, Control4, builds complete ZigBee-based systems; but you must acquire it from a contractor who will handle the installation (charging you handsomely and limiting your expansion options in the process).

Few ZigBee devices are sold at retail today, and none of the Mac home-control software programs we looked at are capable of operating a ZigBee network yet. Still, ZigBee’s status as an IEEE standard carries a lot of weight, and that could make it a major contender down the road.

Z-Wave

Z-Wave is a proprietary wireless home-control standard developed by Zensys, and it enjoys robust support from more third-party manufacturers than either Insteon or ZigBee. Cooper, GE, Intermatic, and Leviton offer comprehensive Z-Wave lighting controls; Wayne-Dalton builds garage-door openers; Schlage manufactures door locks; and so on.

Control your home's temperature with this Z-Wave thermostat from Trane.

You can buy nearly all these products at retail, but Wayne-Dalton’s HousePort and TrickleStar’s Z-Wave widget are the only Mac-compatible home-control programs we’re aware of, and they’re both very rudimentary. But Z-Wave has gathered more industry-wide momentum than either Insteon or ZigBee (including a critical endorsement from Intel), which could help it become the eventual home-control standard. Hybrid ZigBee/Z-Wave systems are also an option--Control4, for instance, introduced a bridge device late last year that enables its ZigBee system to control Z-Wave devices. Handy.

The Future Awaits…

Even more good news: There’s no need to make a decision just yet. In the next few pages, we’ll outline the most useful automation options for everything from automatically turning on your lights to amazingly simple webcam security to streaming video servers. Once you decide what’s right for your home, refer back to this primer to decide which hardware standard and corresponding software is right for you. Then it’s time to get your DIY on… even if doing it yourself amounts to Googling “professional home automation installers.”

Home-Control Software

You'll need to manage your entire home-control system by running software on your Mac that "talks" to your various interfaced devices. The major software players are:

Indigo: Perceptive Automation’s Indigo Lite ($89.95) is compatible with Insteon and X10 modules, but not ZigBee or Z-Wave. It includes both a built-in web server and client/server architecture, so you can control the entire system locally or remotely. You can also schedule events (turn on the outside lights at dusk), set up triggers (send an email message if a door sensor is activated; monitor and program your Insteon thermostat), and more. Indigo Pro ($179.95) adds a host of advanced features, such as voice-command response. You can also control Indigo with your iPhone using the free app Indigo Touch.

Indigo's software enables you to control your system remotely.

XTension: Sand Hill Engineering’s XTension ($149.95) is compatible with X10 devices, several RF and niche interfaces, and certain wireless weather-monitoring products manufactured by Oregon Scientific. A technically savvy audience--even home automation contractors--will find a lot to like, but the software doesn’t support ZigBee, Z-Wave, or Insteon modules, which is… odd.

Thinking Home: Always Thinking’s Thinking Home ($79) works with X10 and Insteon modules, but not ZigBee or Z-Wave devices. It’s not as sophisticated as Indigo, but it covers the basics and boasts an easy-to-learn user interface.

I completely agree with the above comment, the internet is with a doubt growing into the most important medium of communication across the globe and its due to sites like this that ideas are spreading so quickly.

Want to rip music video off iPhone onto Mac? Lose your music video files when Mac computer crashed? As iTunes keep us from transfering files from iPhone to Mac, we have to turn to a third party transfer software. I'd like to recommend Joboshare iPhone Rip for Mac.

It is an amazing handy iPhone rip, iPhone backup software that can fast rip, copy, transfer and manage your music, videos, photos, podcasts and TV Shows between iPhone and Mac with ease.
